#2.1077*10^24 "molecules" SO_3#

#8.4308*10^24"atoms"#

Explanation:

Using Avogadro's number, #6.022*10^23#, convert moles into molecules
Because a mole means that there are #6.022*10^23# items in it, multiply the number of moles by Avogadro's number.
#3.5molSO_3 * 6.022*10^23 = 2.1077*10^24 "molecules" SO_3#

To convert from the number of molecules into atoms, count how many atoms per molecule, in this case: 4. Then, multiply by the number of molecules:
#2.1077*10^24 "molecules" SO_3 * 4 = 8.4308*10^24"atoms"#
